FIELD OF THE INVENTION

The present invention relates to a case, having a soft protective cover and a hard protective frame, for an electronic device and, more particularly, to a mobile phone case having a soft protective cover and a hard protective frame with a number of mating means for secure coupling between the soft protective cover and hard protective frame.

BACKGROUND OF THE INVENTION

Mobile electronic devices such as mobile phones, smart phones, tablet computers, MP3, PDA and the like are in wide use around the world. A user grips such device in his hand or hands to use it and uses his fingers to use various applications of the device. However, while using the device, the user may accidentally drop the device thereby causing damage to the device. In addition, use of mobile electronic devices may cause hand, limb and back problems due to the physical stress of holding the electronic device for an extended period of time.

Users of the mobile electronic devices use cases to protect their devices and manufacturers have produced different types of cases to help the users protect their mobile devices. One type of such cases is the one comprised of a soft protective cover and a hard protective frame in which the hard protective frame encircles the side portions of the soft protective cover as shown in FIGS. 1(a) and 1(b). Generally, the side portions of the soft protective cover have upper and lower ledges and the hard protective frame is received in between the two ledges and applies pressure to an electronic device installed in the soft protective cover. The hard protective frame is securely received in between the two ledges and is not easily dislodged.

However, the hard protective frame has holes for connector, speaker, earphone or other buttons, and the portions for such holes are manufactured thinners than other portions. Accordingly, such portions are more susceptible to damages or breakage. In addition, many cell phones necessitate a case to have several holes on its bottom side portion for charging cable, speaker, or earphone, and the bottom side portion of a case becomes especially more vulnerable to damage or breakage.

Therefore, to solve the problems, there is a need for a case of a soft protective cover and a hard protective frame to have structurally reinforcing elements. This invention is directed to solve these problems and satisfy the long-felt need.

SUMMARY OF THE INVENTION

The present invention contrives to solve the disadvantages of the prior art. The present invention provides a case, having a soft protective cover and a hard protective frame, for an electronic device and, more particularly, to a mobile phone case having a soft protective cover and a hard protective frame with a number of mating means for secure coupling between the soft protective cover and hard protective frame.

The object of the present invention is to provide a case for an electronic device, comprising: a soft protective cover having a back panel to cover a back portion of the electronic device and side walls extending from the back panel to cover side portions of the electronic device; a hard protective frame, constructed to removably mount on the soft protective cover and wrapping around the side walls of the soft protective cover, wherein the hard protective frame comprises a disconnected side and two facing sides, wherein the disconnected side is disconnected and has a first end portion and a second end portion; and a first mating means formed on the first and second end portions of the hard protective frame and corresponding portions of the side wall of the soft protective cover.

Another object of the present invention is to provide a case comprising a soft protective cover, a hard protective frame and a first mating means, and further comprising a rib connecting two facing sides of the hard protective frame.

The advantages of the present invention are: (1) the hard protective frame is securely and tightly coupled to the soft protective cover; (2) the case having the soft protective cover and hard protective frame provides effective protection to an electronic device installed therein; (3) the hard protective frame is not easily dislodged from the soft protective cover; (4) the soft protective cover and hard protective frame are very easy to assemble and dissemble; and (5) the coupling structure of the soft protective cover and the hard protective frame provides a stylish appearance.

 18. A case (10) for an electronic device (100), comprising: a soft protective cover (20) comprising a back panel (21) covering a back portion (110) of the electronic device (100) and side walls (22, 23, 24, 25) extending from the back panel (21) to cover side portions (120, 130, 140, 150) of the electronic device (100); and a hard protective frame (30) constructed to mount on the soft protective cover (20), the hard protective frame (30) comprising: a disconnected side (35) including a first end portion (36) and a second end portion (37); two facing sides (33, 34); and a rib (80) connecting the two facing sides (33, 34) of the hard protective frame (30), wherein the rib (80) is formed right next to the disconnected side (35), and wherein the rib (80) is wider towards the two facing sides (33, 34) such that the rib includes a first rib end that extends from the first end portion (36) of the disconnected side (35) and a second rib end that extends from the second end portion (37) of the disconnected side (35).
 19. The case (10) of claim 18, wherein the hard protective frame further comprises an opposing side (32) which is opposite to the disconnected side (35), wherein the opposing side (32), the disconnected side (35) and the two facing sides (33, 34) of the hard protective frame (30) wrap around the side walls (22, 23, 24, 25) of the soft protective cover (20), wherein the hard protective frame (30) is constructed to removably mount on the soft protective cover (20), wherein the hard protective frame (30) does not substantially cover a back portion (21) of the soft protective cover (20), and wherein the soft protective cover (20) further comprises a groove (29) formed on the back panel (21) of the soft protective cover (20) for receiving the rib (80).
 20. The case (10) of claim 19, further comprising a first mating means (40) formed on the first and second end portions (36, 37) of the hard protective frame (30) and corresponding portions of the side wall (25) of the soft protective cover (20), wherein the first mating means (40) comprises first mating protrusions (43), formed on the first and second end portions (36, 37) of the hard protective frame (30), and first mating holes or recesses (42), formed on the side wall (25) of the soft protective cover (20), wherein the first mating protrusions (43) are mated with and substantially received in the first mating holes or recesses (42), wherein the case (10) further comprises a fifth mating means (90) formed on the rib (80) of the hard protective frame (30) and corresponding portions of the soft protective cover (20), wherein the fifth mating means (90) comprises fifth mating protrusions (93), formed on the rib (80) of the hard protective frame (30), and fifth mating holes or recesses (92), formed on the groove (29) of the soft protective cover (20), and wherein the fifth mating protrusions (93) are mated with and received in the fifth mating holes or recesses (92).
